Dan Osborne almost missed the birth of his third child by choosing to fly thousands of miles away for a stag do with mates while wife Jacqueline Jossa battled to get through the last few days of her pregnancy.

The ex-TOWIE hunk had jetted to Las Vegas earlier this month to celebrate his friend's last days of singledom, despite knowing Jacqueline was just 12 days from her due date.

And while Jac didn't give birth to their second daughter together - Dan also has son Teddy, four, from a previous relationship - until Monday June 25, his decision to spend time away from his estranged partner raised eyebrows.

Topless Dan was spotted chatting away to a bevy of bikini-clad women at a pool party in Vegas on his mate's stag, while back home Jac was coping with three-year-old Ella and the aches and pains associated with late-stage pregnancy.

He even missed Father's Day on June 17, instead being seen putting his arm around various women wearing swimsuits and even leaving with a group of ladies on their party bus.

But Dan, 26, furiously hit back after fans criticised his decision to leave the kids at home and booze it up in Vegas on the special day.

"I post a picture of my beautiful children, that I'd do ABSOLUTELY ANYTHING for, who I love more than anything on earth! Who I think about every minute of every day," he wrote on social media.

"Then have random w**kers that do not know me, saying I'm a s**t dad, my children are unlucky to have me as a dad, that I'm just a sperm donor etc."

He carried on: "I don't know why I'm reading these things, [they] hurt me because I know it isn't true and these people don't know me, f**k off you nasty disgusting people.

"My children are my absolute world, everyone that knows me knows how much I adore my children. No matter what has happened in past relationships or whatever, it does not make a s**t dad, I'LL ALWAYS do everything I can for my children and I'll make sure they are happy as they possibly can be!"

Dan then furiously added: "How a relationship plans out does not change how someone is as a parent, there are millions of great dads out there that unfortunately aren't lucky enough to spend every single day with their children etc.

"No one wants to live in a separate home to their children or not be able to put them to bed every single night, but sometimes it's how it is and then all we can do is be the best dads we can be.

"Anyway, happy Father’s Day to all the good dads out there, we are all truly blessed."

His angry rant came shortly after Dan said he was ready to put himself first following months of unhappiness and rowing in his 11-month marriage.

In a searingly honest interview - which hit close to the bone for many of Jacqueline's supporters - Dan said "life's too short" to be trapped in a miserable relationship.

"I left because we were arguing and it is such a waste of energy," he told Daily Star Sunday.

"The way I look at life is every day spent unhappy is a wasted day, and we were both having a lot of unhappy days. I still obviously care for Jacqueline but if we can't make each other happy then we shouldn't stay together. Life is too short."

And he vowed to put himself first, revealing he'd rather go out with his mates than stay at home with his wife and children in a toxic atmosphere.

"We argue at home so I go out because I don't want to be home arguing when I can be enjoying myself with mates," the reality star added.

"I will move back to help before the birth and with the baby, but I don't know after that. The main priority is the kids."

Jacqueline was said to be hurt by his interview, especially as she gave a separate one saying they'd been getting on well and neither of them knew what would happen in the future.

Since returning home from Vegas last Thursday, Dan is said to have moved back into the marital home with Jacqueline and Ella to help with the tiring newborn stage.

The couple are yet to announce their chosen name for their newest baby girl, whose sex was kept secret throughout Jac's pregnancy.
